SPECIFICATION forming part of Letters Patent No. 787,617, dated April18, 1905.

Application filed November 7, 1904. Serial No. 231,774.

To all whom it may concern.-

Be it known that 1, JAMES P. SMITH, a citizen of the United States,residing at Raeford, in the county of Cumberland and State of NorthCarolina, have invented a new and useful Plow, of which the following isa specification. Y

This invention relates to plows, and has for its object to improve theconstruction and increase the efficiency and operativeness withoutmaterial increase in the expense of manufacture.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same consists in certain novelfeatures of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which corresponding parts are denoted by likedesignating characters,is illustrated the preferred form of the embodiment of the inventioncapable of carrying the same into practical operation, it beingunderstood that the invention is not necessarily limited thereto, asvarious changes in the shape, proportions, and general assemblage of theparts may be resorted to without departing from the principle of theinvention or sacrificing any of its advantages.

In the drawings, Figure l is a side elevation with the plow in section.Fig. 2 is a bottom plan view with the standard adjusted to its lowerposition or in position to provide for the transportation of theimplement. Fig. 3 is a detail side view illustrating the adjustment forelevating the point of the moldboard above the heel-plate. Fig. 4 18 asectional detail on the line 4 4 of Fig. 1. Y

The beam 10 of the improved plow is pref.- erably of steel, curvingdownwardly at the rear end and provided with means, such as a hook 21,for attaching the draft-animals in the usual manner. The heel end of thebeam is provided with a circular cavity 23, having convex sides andadapted to receive a circular stub 12 on the rear end of a heel-plate11, the stub being concaved to correspond to the convex interior surfaceof the cavity. The cavity.

will be first formed with its inlet as large or larger than the interiorto freely receive the stub, and then after the latter is inserted theextremity 24 of the cavity will be bent upward by force to decrease theinlet and prevent the withdrawal of the stub and attached heel-platelongitudinally, while the coacting concave and convex surfaceseffectually pre-' vent lateral movement. Thus the heel-plate is free toswing vertically upon the heel end of the beam, but is firmly held from.lateral movement.

A standard 13 is provided in elongated U form and pivotal ly connectedto opposite sides of the forward end of the heel-plate, as at 14, andembracing the opposite sides of the beam by the spaced sides near theclosed end. The standard is provided with two set screws, one, 15,hearing against the outer face of the beam and the other, 16, bearingagainst the side of the beam, and the two sides of the standard are alsoconnected beneath the beam -by a transverse stop 17 for bearing againstthe beam.

The moldboard 18 is secured to the standard in the usual manner by aheel-bolt 19, and the handles 20 are also attached in the usual mannerto the beam. 1

The curve of the beam 10 is eccentric to the pivot-point 14 between thestandard and heelplate, the beam being farther from the pivot 14 at theheel end of the beam than at the forward end of the curved portion, sothat as the standard is elevated toward the perpendicular the draft end21 of the beam will be elevated correspondingly by the pressure of thestop 17 upon the under side of the beam. By this arrangement it will benoted that the pitch of the moldboard may be adjusted to any requiredextent by moving the standard along the curved portion of the beam andheld firmly at any desired point by the set-screws 15 16. It will alsobe noted that the action of adjusting the standard and moldboard willcorrespondingly adjust the draft end of the beam vertically by reason ofthe eccentric curve of the beam, as before noted. An additionaladjustment may also be secured by means of the rear set-screw 15 to anextent equal to the movement of the beam within the area between thestop 17 and the closed upper end of the standard.

Another adjustment which may be quickly accomplished and which is a veryimportant and valuable feature of the invention is to loosen both theset-screws 15 16 and permit the standard and its attached moldboard tofall to the lowest point, as indicated in Fig. 3, which action throwsthe point 22 of the moldboard out of the ground or above the lower lineof the heel-plate, so that the implement may be easily transportedwithout danger of the moldboard cutting into the ground. This is a veryuseful and convenient advantage when the plow is tobe moved from placeto place, as will be obvious.

The device is simple in construction, strong and durable, can beinexpensively manufactured, and will be found very effective in action.

The adjusting-screws l5 16 are provided with relatively largehand-wheels to facilitate the operation, and being located above and atthe side of the beam are easily accessible to the operator from hisposition at the rear.

Having thus described the invention, what is claimed is 1. In a plow, acurved beam having a heelplate pivotally connected with its lower end,

an elongated U-shaped standard straddling the beam and connectedpivotally by its spaced ends with opposite sides of the forward end iand which is thereby adjustable by said standard, and means for securingthe latter in adjusted position with relation to the beam.

2. In a plow, the beam having a transverse socket-cavity in its heel endwith convex walls, a heel-plate having a stub at one end for engagingsaid cavity and with concave sides corresponding to the convex walls ofthe cavity said socket-cavity adapted to be closed around said stubportion by compressing the beam material at one side of the cavity, astandard connected to swing from the forward end of said heel-plate andadjustably associated with said beam, and a moldboard connected to saidstandard.

In testimony that I claim the foregoing as my own I have hereto afliXedmy signature in the presence of two witnesses.

JAMES P. SMITH.
